Yes, i know EXACTLY what you mean.
St. Vincent hospitals take you on a sliding scale fee, and the St. Vincent Stress Center in Indianapolis is an exact place that will take you on a sliding scale. they have okay food, and great care. And they only keep you as long as you need. I've seen people leave within 3 hours, and stay up to 2 weeks. (unless your waiting for another place such as in a state hospital, then you could be there for a month to 5 months.)
But they are very nice and friendly there.
They also have outpatient services.
